Install plugin inside geoserver cloud

[turdusmerula]

I need to add several plugins to my geoserver instance:

• a keycloak plugin https://docs.geoserver.org/latest/en/user/community/keycloak/index.html
• a netcdf plugin https://build.geoserver.org/geoserver/2.21.x/ext-latest/](https://build.geoserver.org/geoserver/2.21.x/ext-latest/geoserver-2.21-SNAPSHOT-netcdf-plugin.zip

So far I don't quite understand how to add these plugins to the cloud version of geoserver. Can you provide a general way or some hints to integrate a plugin inside geoserver?
I think this is quite a duplica of #224 but the goal is to generalize plugin integration.

Hello, same for me i need to install https://docs.geoserver.org/maintain/en/user/extensions/importer/installing.html
There is a way to link WEB-INF/lib folder to host ?

@MkLHX the importer extension is already integrated, you just need to enable it.
In docker-compose.yml you can add the following env variable to the web-ui service:

webui:
    environment:
      WEBUI_IMPORTER_ENABLED: "true"

Or modify the geoserver.yml externalized configuration

geoserver:
  web-ui:
    extensions:
      importer.enabled: true

@turdusmerula gscloud requires each extension to be integrated explicitly through a spring-boot autoconfiguration. Just dropping a geoserver plugin to the classpath won't work because we don't do component scanning through applicationContext.xml, in order to be able to cherry picking exactly what to import to the spring application context and use externalized configuration.

If you have coding capabilities a pull request is always welcomed.
For NetCDF threre's already a ticket (#138 ) but no formal commitment to integrate it yet.

For Keycloak you can create a ticket labeled as feature. This (and any other additional authentication plugin) one is tricky, cause by one side I'd rather delegate authentication to the gateway instead of having to integrate all possible authentication mechanisms on all services, but on the other side I don't currently have the bandwith to work on that.

Thank you.

Where can i find the documentation about geoserver cloud environement variables list?

Hello, @groldan

I'm doing this message, just to be sure you got my question the last time:

Where can I find the documentation about the geoserver cloud environment variables list?

Because I need to install/activate the INSPIRE plugin, I don't know where to find the .env variable about this option.

[groldan]

it boils down to whatever config you have in the externalized configuration, see https://github.com/geoserver/geoserver-cloud-config/blob/master/geoserver.yml

given the way spring-boot config works, you can replace any of those config properties with environment variables (capitalizing them and replacing . by _), or through Java System Properties (no change in the name required here).

For some of them we use shorter placeholders (${placeholder[:<defaultValue>]}), for example in:

geotools:
  httpclient:
      http:
        host: ${http.proxyHost:}

you don't need to provide the full geotools.httpclient.http.host property name, but just http.proxyHost (or HTTP_PROXYHOST env variable)
